Why Fasting on Mondays is Dedicated to Shiva (Somvar Vrat)

Why Monday specifically

The Sanskrit word for Monday, "Somvar," derives from "Soma," a name associated with the moon. Since Shiva wears the crescent moon in his hair (Chandrashekhara, "the one who holds the moon"), Monday came to be associated with him specifically, distinct from other days linked to different deities in the broader Hindu weekly calendar.

What the fast typically involves

Somvar Vrat can be observed with varying degrees of strictness, and there's no single mandatory format. Common approaches include:

A full fast, taking only water or nothing at all until evening worship is complete.

A partial fast, allowing fruits, milk, or specific non-grain foods throughout the day.

A single-meal observance, eating one satvik (pure, simple) meal in the evening after completing prayers, avoiding grains, onion, and garlic.

The stricter forms are traditionally reserved for those with existing devotional discipline or specific vows (sankalpa), and there's no expectation that a first-time observer needs to attempt the most demanding version.

The devotional practice alongside the fast

Fasting alone isn't considered the complete observance. Somvar Vrat typically includes visiting a Shiva temple or performing puja at home, chanting Om Namah Shivaya or the Shiva Chalisa, and performing abhishekam if possible. The fast supports the devotional focus of the day rather than standing alone as the practice itself.

Why fasting is considered significant

Beyond the specific association with Monday, fasting more broadly is understood in this tradition as a discipline of the body that supports discipline of the mind. Reducing the demands of digestion and appetite is believed to free attention for prayer and reflection, a practical rather than purely symbolic rationale behind the practice.

Some devotees observe Somvar Vrat for a fixed number of consecutive Mondays (16 is a common number, tied to a specific vow called Solah Somvar Vrat) as part of seeking a particular blessing or resolving a specific difficulty, concluding the observance with a final, more elaborate puja.

Starting the practice

If you're new to Somvar Vrat, there's no requirement to begin with the strictest version. A single day of mindful eating, extended prayer, and quiet reflection on a Monday is a reasonable starting point, one that can be deepened over time as the practice becomes more familiar.
